mam. e1.221* -15 This invention relates to faucets, and particularly toone intended for use on a liquid container from which the liquid isintended to be.

dispensed by inversion of the container. Distilled water, for instance,is commonly distributed to individual usersin containers intended to beso used; a crock having a faucet therein being usually supplied to theuser, the crock supporting the container in an inverted position. It isone of the objects of my invention to pro vlde a dispensingfaucetadapted to be removably and directly applied to the neck of thecontainer,

so that the need of a crock or similar vessel is unnecessary. l

A further object of my invention is to provide a faucet for the purposewhich admits air to the container as the liquid is withdrawn therefromin such a manner that an even andsmooth inflow of air without buckingthe liquid is obtained, insuring an even flow-of liquid from thecontaner. j

, A further object of the invention is to produce a simple andinexpensive device and yet one which willnbe exceedingly effectiveforthe purpose for which it is designed.

These objects I accomplish by means 0:5 such 1 structure and relativearrangement ofparts as will fully appear by a perusalof, the, followingspecification and claimspl M I In the drawing similarchara'cters ofreference indicate corresponding parts in the several views 2 Figure '1is a sectional elevation of the faucet v connected to the neck of abottle, the faucetbeing closed.

Referring now more particularly to the characters of reference on thedrawing, and describ-' ing the, faucet as in its normal or dependingposition relative to the container, the faucet vcomprises a liquidoutlet tube I depending from an enlarged flange 2. This flange issubstantially the diameter of theneck 3' of the bottle 4 or othercontainer to which thejfaucet is intended to be applied.- A resilientwasher'5 is disposed between a the flange and the rim of the neck, theflange being clamped against the 'washerfl to give a liquidtight fit bymeans ofa screw cap-or ring nut member 6 adapted to engage the threads Iprovided'on the neckl i I Projecting into the neck from the. flange 2 inclearance relation to said neck is anopen ended .tube'8. This isconcentric with tube l, and somewhat larger in diameter. flange isanother tube 9, which practically an Figure 2 is a similariview, showingthefaucet ing the. same,

Depending from theextension of tube, 8, and which surrounds the tube Iin concentric and clearance relation thereto. This tube 9 is somewhatshorter than tube I, and is provided about its lower edge with aresilient ring gasket l0. Air bleed holes ll extend through the flangeso as to lead from between the tubes I and 9 to the outside of tube 8,the number of these holes being such as to provide 'an air intakeareasuflicient to compensatefor the ,1

amount of liquidwithdrawn from the outlet tube I. Y a

Normally engaging the gasket It! in sealing relation is'a cupped closuredisc I 2, formed, with a central depression I3 to receive the projectingvided at the top with an outwardly'projecting flange- I1 which slidablyengages a skirt l8 formed and depending from the cap 6. Acompressionspring 19 is disposed about the member l6 inside skirtl8,andJat its ends engagesthe flange H andan inwardly'projecting flange 20on'the lower edge of the skirt and which also guidesjthe member "5.Theflanges l1 andHZU from exteriorally of, the faucet to the space be-.tweenjmembers l6 and 9. I a

the disc, is attached "to; a tubular member l6 which-extends abouttubev9 in a clearance relation thereto and which is proare both notchedor otherwise cut away at me tervals so' asto provide for a' free flow ofair In operation, the spring normally acts to hold v the valvediscagainst the gasket I), thus pre'-.

venting any air from gaining access to the '-c'ontainerv andof coursepreventing liquid from leav When the' nozzle. is pulled" down, agate theresistance of the spring, the valve disc is lowered fromv engagementwith the gasket. Air canthen enterthe container 4 from'th'e outside,passing down" between members 9',and 5,. under the gasket, and then upbetween the tubes. I and 9 and into the container on the outside of tube8 through passages l l. Theincoming air of course allows the liquid ,toflow from the faucetthroughtubes 8 and I, over the valve disc andthrough passages l5 to the, nozzle, outlet.

thernozzle being thus interrupted, a smoother Thedirect downward flow ofthe liquid from- A v and softer flow from the nozzle is obtained,without any loss of volume.

Due to the fact that the liquid outlet tube l terminates below the airintake tube 9, and that the highest point of the valve disc (over whichthe liquid must flow) is below the closure gasket when the faucet isopen, the outgoing liquid on the disc does not interfere with the flowof air in the opposite direction into the tube 9.

Due to the large size of the liquid outlet tubes 8 and I relative to theair intake holes ll, practically all the liquid takes the path of leastresistance and passes down through said tubes rather than through theholes. air intake space between the tubes I and 9 relatively empty ofliquid, so that the desired inrush of air into the container throughsaid holes is" unrestricted. Also, since the air enters the containerclear of the ,path of the main body of downwardly flowing liquid, suchliquid offers no interference to the intake of air. As a result, aliquid flow of substantially constant volume is obtained.

As will be particularly clear from Fig. 2, the flange 2 of the tube unitis clamped in place. by the removable cap or nut 6. Removalof this nuttherefore enables the tube unit to be withdrawn from the remaining partsof the faucet assembly. This facilitates sterilizing operations, as wellas making it very easy to replace the gasket Ill Whenever necessary.

From the foregoing description it will be readily seen that I haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice suchdeviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.
